Naomi not Nicole

Naomi Watts is fed up with being mistaken for best friend Nicole Kidman.

The Oscar-nominated actress says she can't understand why people get her and Nicole confused as they don't really look like each other.

She said: "We don't even look like each other. We might have similar mannerisms, but we're very different. We grew up in different ways. We're friends, so maybe we've been influenced by each other because of that."

The pair first met on the 1991 movie 'Flirting' and have been pals ever since.
